The data in Victoria Unearthed comes from a range of existing sources.
- EPA Environmental Audits
- Groundwater Quality Restricted Use Zones
- Victorian Landfill Register
- Environmental Audit Overlay
- Historical Business Listings
The various datasets in Victoria Unearthed have different degrees of accuracy and reliability.
For example, the Historical Business Listings from the old Sands & McDougall directories are a record of historical business locations in Victoria. These directories have presented particular challenges regarding data accuracy as Victoria's street names and numbers may have changed drastically over the past century, and so has the way we record information.
The Victorian Landfill Register (VLR) was created by EPA in 2018. At its first release, the VLR dataset only included information about landfills that could be suitably verified.
If EPA could not validate details of a suspected landfill site, this site was not included in the VLR at this first release.
Environmental Audit Overlays, Groundwater Quality Restricted Use Zones (GQRUZs) and EPA Environmental Audits are a snapshot of information at a certain point in time and do not establish current contamination. Some GQRUZs that were applied between 2007 and 1 January 2014 may not have their corresponding environmental audit reports linked to them in Victoria Unearthed. This is because these reports were developed under a different system and are held manually by EPA. These can be obtained by calling EPA on 1300 372 842 and requesting a copy of the report.
Details about each dataset are available via the links below.
